PIC12C5XX

PIN COMPATIBILITY

Devices that have the same package type and VDD,

VSS and MCLR pin locations are said to be pin

compatible. This allows these different devices to

operate in the same socket. Compatible devices may

only requires minor software modiﬁcation to allow

proper

operation

the

application

socket

(ex., PIC16C56 and PIC16C61 devices). Not all

devices in the same package size are pin compatible;

for example, the PIC16C62 is compatible with the

PIC16C63, but not the PIC16C55.

Pin compatibility does not mean that the devices offer

the same features. As an example, the PIC16C54 is

pin compatible with the PIC16C71, but does not have

an A/D converter, weak pull-ups on PORTB, or

interrupts.
